​Digital music now comes from a multitude of sources, but your PC’s sound card is an afterthought. Pass the same file through the 851D’s twin DACs in dual differential mode and its 2nd generation Adaptive Time Filtering process and the music will sound extraordinary – just as the original artist intended.

We built the 851D using all our hi-fi know-how, so it has a large toroidal transformer, audiophile internal components and connectivity with as many sources as possible. There are digital TOSLINK, S/PDIF, BNC and AES/EBU inputs, while if you add a BT100 Bluetooth dongle you can pair with compatible devices. For your PC there’s an asynchronous USB audio input with a dedicated driver, allowing you to bypass the PC’s poor audio path.

The outputs are similarly designed with flexibility in mind, with both digital, balanced XLR and traditional RCA sockets. As the 851D is also a pre-amp so can be directly connected to a power amp such as our 851W or active speakers for further sonic benefits.​
